There is a coiled spring 21 arranged to surround the tool 18 and to lie loosely in the bore 17 and this spring is adapted to be compress d between the flange 20 and between the nut 22 which is threaded into the enlarged upper end of the bore 17. 7

There is another spring 23, preferably stifier in action than the spring 21, and this also surrounds the tool 18 and it is adapted to be compressed between the lining sleeve 19 at the bottom and between the flange 20 on the tool. There is pivoted by means of the pin 24 to the upper end-of the tool 18 a rod 25 which is adapted to place the tool 18 either into or out of operative relation with the operating lever '4'. The lower end of the plunger 10 is provided wlth a rounded projection 26 and a shoulder 2? which are adapted to co-operate with the hollow post of an eyelet for the purpose of upsettingthe end of the eyelet as described in my said co-pending application. 'The lower end of the tool 18 is preferably chamfered, as shownat 28, to form the cutting edge, and this end of the tool is adapted to enter a perforation 29 in the base. 1 as the tool passes through a sheet of paper or other material placed upon th base 1.

Assumingthat the first operation to be performed is that of perforating one or more sheets of paper or other material to provide an aperture for an eyelet, the perforatng tool will be placed in the operative condition shown in Figures 1, 1 and 5. i This is done by turning the member 25 into a vertical position'in line with the tool 18 and when the member 25 is in thevertical position the spring 21 presses on the flange 20 to hold the tool 18 depressed slightly, so that the pin 2t lies slightly below thenut 22 and while this condition exists the member 25 cannot move laterally because the portion 30 of the member 25 is prevented from swinging laterally within the housing. J

If a sheet of paper or other materia to be perforated is placed on the bed 1 and the lever 7 is depressed, it will press downwardly on the member 25 thereby moving the tool 18 downwardl until the lower end asses through the paper or other material into the aperture29 of the base and in doing so the tool cuts an aperture in the paper or other material. The plunger 10 is also moved downwardly in this operation, but its lower end does not come into contact with the base 1 when the tool 18 is in its lowermost position, as shown in Figure 5, and therefore, the plunger 10 merely touches or presses on the paper without performing any operation. When the handle 7 is released, the tool 18 is retracted by the spring 23 and the plunger 10 is retracted by the spring 11 the latter also servin to retract the lever 7.

After this perforating operation has been performed, an eyelet may be inserted through the perforation in the material whereupon the same is placed on the base 1 with the post of the eyelet directed upwardly and in line with the plunger 10. To avoid cutting a separate aperture in the material, the perforating tool is thrown out of operation.

This may be done by lifting the member 25 and the tool 18 against the opposition of the spring 21 to raise the pin 24 and the end 30 of the member 25 out of the bore 17, whereupon the member 25 is turned on the pin 24: into the position shown in Figure 3. The end 30 of the member 25 will then rest on the nut 22 and will be held there by the downward pressure of the spring 21 so that the member 25 remains in the horizontal position shown in Figure 3. The plunger 10 may now be operated and the tool 18 will not be operated because the member in operative relation with the lever 7.

As the handle 7 is depressed the plunger 10 is moved downwardly in opposition to the spring 11 and the lower'end of the plunger acts to turn over the upper end of the hollow post of the eyelet in similar manner to other types of eyeleting machines.

The ball. 14 prevents any binding action between the lever 7 and the plunger 10 so that the device operates with a minimum of resistance even though the surface 16 is not perfectly machined. To return the perforat ing tool into active relation with the lever 7, the member is swung upwardly into vertical position and when the end 30 swings into the bore 17 the tool 18 and the member 25 are slightly depressed by the spring 21 until overcome by the resistance of the upwardly acting spring 23. This will again move theend 30 and the pin 24 within the bore 17 to prevent lateral movement of the member 25. The tool will then be returned to the condition shown in Figure at and the perforating tool may be used as previously described.

Having described my invention, what I claim is 1. A machine of the class described having frame, a plurality of reciprocating tools, an operating lever for operating one or both of said tools, and means permitting a portion of one of said tools to befolded over with respect thereto to take it out of operation by said operating means.

2. A machine of the class described, comri a frame, a plurality of adjacent tools adapted to reciprocate in said frame, and an operating member adapted to operate on both 1 tools, one of said tools having a jointof said 25 is no longer ed section adapted be foldedover to take said tool out ofbperative "relation to said operating means.

3. A machine of theclass described comprising a frame, a plurality of adjacent tools adapted to reciprocate 111 said frame, and an I operating lever adapted to simultaneously operate both of said tools, one of said tools having a jointed section and adapted tobe folded over to take said tool outof operative relation with said lever.

4. A machine of the class described includinga frame, a plurality of tools arranged adjacent each other and adapted to reciprocate in said frame, springs for retracting said tools, and a lever adapted to simultaneously operate said tools in one direction, one of said tools including a pivoted member adapted to be folded over to take it out of operative relation with said lever.

5. A machine of the class described comadapted to operate on said pivoted member when the same is in alignment with the tool. and to be inoperative when said plvoted member is swung laterally.
